Recently, Guangdong Yulun Intelligent Technology Co., Ltd. (hereinafter referred to as "Yulun Machinery") paid a visit to Hunan University of Science and Technology, simultaneously advancing the co-construction of the "Integrated Internship and Employment Base" and the 2026 campus exclusive recruitm
From May 19 to 22, Guangdong Yulun Intelligent Technology Co., Ltd. (hereinafter referred to as "Yulun") successively visited Foshan Gaoming Technician College and Guangdong Polytechnic College, and held in-depth exchanges on deepening university-enterprise cooperation and precisely matching talent
Upgrading mattress manufacturing equipment demands high capital expenditure (CAPEX). Factory managers cannot afford to make equipment decisions based purely on promotional brochures. We must look deeper into actual performance data.
Scale mattress production with a Pocket Spring Assembly Machine. Reduce labor costs, minimize material waste, and improve precision zoning for profit.
Discover why pocket spring mattresses stay quiet, how to fix common bed squeaks, and why your frame might be the real source of nocturnal noise.
Optimize mattress production with pocket spring assembly machines. Learn to boost throughput, ensure precise zoning, and reduce glue waste by 40%.
China‘s black technology, a revolutionary breakthrough in spring machines!
You can save more than 20% of the steel wire cost while achieving a similar mattress rebound effect for each mattress .
1. This is a spring machine that can produce high compression ratios as well as conventional springs.
2. This machine adopts the latest mechanism and technology, which can provide greater compression of the spring to meet the goal of saving steel wire costs.
3. We can customize the machine to produce high compression springs of 35 cm after pocketing according to clients’ requirements, which will give clients a cost advantage in producing mattresses
High pocket springs can be used in furniture manufacturing, especially in the production of roll-packed sofas and mattresses

Save manufacturing material costs: Due to the higher height of pocket springs, the use of filing materials can be reduced,for example, if producing 14 inch high mattresses, 30-32cm high pocket springs can be used to save filling materials (such as sponge, latex….; if producing roll-packed sofas, using 30-35cm high pocket springs for seat cushions, which can save about half of material costs compared to traditional high-density sponges.( High springs cost about RMB 230/m³,high-density sponge costs about RMB 550/m ³)
Save logistics and warehousing costs: Roll-packed sofas, similar to rol-packed mattresses, their volumes are greatly reduced , which can save a lot of space during transportation, thereby reducing logistics costs and making them easy to carry: similarly, due to the reduction involume,the costs of warehousing also decreases.

1. Both high compression springs and conventional springs can be produced.
2. Under similar resilience effects,the high compression pocket springmattresses produced can save over 20% of steel wire costs compared toconventional pocket spring mattresses.
3. Both cross-welding and edge-welding are driven by servo motors (rather thancylinders), which saves electricity and does not affect production even in lowtemperatures during winter.
4. With less operation pages and less parameters, it is easy to operate and evenbeginners can quickly get started.
5. The machine has a simple structure and is easy to maintain.6. With fewer wearing parts,the daily operating cost of the machine is relativelylow.
